3.0L 12v - M30B30 

The M30B30 is the 3.0 litre version of BMW's 12-valve straight six, a sturdy base that is often taken further.

For this engine our catalogue offers one set of forged connecting rods shared across the whole M30 family: M30B28, M30B30, M30B32 and M30B35. It suits builds that run forged pistons, whether highly tuned naturally aspirated or boosted.

Centre to centre length, con rod bolts and machining tolerances are detailed on the product page. Replacing the standard rod remains the step to take before raising engine speed or torque.
